To all whom it may concern:

Be it known that I, FREDERIC A. FINEGAN, a resident of Flushing, in the county of Queens and State of New York, have invented certain new and useful Improvements in Ventilator Units, of which the following is a specification.

This invention relates to improvements in ventilating units.

The primary object of my invention is to regulate with great rapidity the temperature of a room, store, oflice or the like WhlCh is heated by a ventilator unit located in the same, and in a more intense aspect, the objects of my said invention are to vary instantly the temperature of the air supplied to a room or the like by the blower of such a unit; to divide the air supplied by such a' blower into two downwardly-moving streams, one of which is a main stream heated by a suitable heater and the other of which is a cold-air shunt-stream; to clean or free from dust ,both streams of air; to cause the shunt stream to traverse the path of the heated stream transversely in order to procure a positive mixture of the two streams of air and to discharge the air thus mixed vertically upward against the ceiling of the room or the like where such air is diffused throughout the area thereof without creating a draft.

In the accompanying drawings, in which similar reference characters designate corresponding parts throughout the several views,

Figure 1 is a vertical section on the line 1-1 of Fig. 3 of a device embodying my invention;

Fig. 2 is a horizontal section on the line 22 of Fig. 1 and Fig. 3 isa vertical section on the line 3-3 of Fig. 1.

Referring now to these drawings, which illustrate a preferred embodiment of my invention, 1 indicates a housing or cabinet which may beof any suitable form and may be made of steel or other suitable material. The housing, as illustrated, comprises front, back and and members suitably secured to each other, mounted upon and secured to a suitable base and havin a removable top of-wood or other materia Said housing is located within a room contiguous to a window B and close to wall A so as to occupy a minimum of space.

The housing 1 has, as shown, an upper compartment 2 and a lower compartment 3 1 separated by a horizontally disposed board 4 mounted on a seat formed of angle bars 5 suitably secured to the side and end members, a pad 6 of felt or like material being inserted between the board 4 and angle iron seat 5 to absorb vibration and prevent noise.

The upper compartment 2 is provided with an air intake or passageway 7 formed by a horizontal duct which is arranged to take fresh air from an open window B.

Within the compartment 2, as shown, are mounted two blowers 8 8 and an electric motor 9 for rotating the same. The blowers 8 8 are of conventional form, receiving air axially at opposite sides and forcing the same downwardly through openings 10 in the separating board 4.

In order to enable the temperature of the air supplied by the blowers 8 8 to be varied instantaneously, my invention contemplates the shunting of a stream of cold air, which is suitably regulated as to volume, to one side of and parallel with a main stream which is suitably heated by a heater, and then causing the shunt stream to traverse transversely the path of the main stream to procure a positive and intimate mixture of the two streams.

In the embodiment of my invention illustrated in' the drawings, the air forced through the openings 10 is divided or split up into two downwardly moving streams, viz. a heated air stream and a cold air shuntstream, and the shunt-stream which is capable of regulation is caused to traverse horizontally the path of movement of the heated air or main stream before the two streams are discharged upwardly through a vertically disposed duct against the ceiling of the room in which the device is located where the mixed air is diffused without creating a draft. I am thus enabled to procure an instantaneous variation of the temperature of the air supplied and heated by a ventilator unit, a positive and intimate mixture'of the two streams, and by disposing a common water-bafile inthe path of both streams, the mixed air may be freed from dust before entering the discharge duct on its upward course.

My preferred means for accomplishing the results hereinabove indicated comprises the rovision within the lower compartment 3 o partitions 14 and 15 so as to form between such partitions a main centrally-disposed heating compartment or duct 11 provided with a heater 11 and communicating with the openings 10 at its upper end; a vertically-disposed discharge duct 12 at one side of the main, air-heating compartment or duct which is open to the room at its upper end and communicates at its lower end with the main compartment or duct only, and a vertically-disposed cold-air shuntduct 13 at the side of the main duct opposite to the discharge duct which also communicates at its upper end with the openings 10, and at its lower end with the main duct. The shunt-duct 13 is provided with a regulating damper 17 at its upper end to vary the supply of air thereto, and the communieating opening between the shunt-duct 13 and the main duct 11 is in horizontal alinement with the opening between the main duct and the discharge duct so as to provide a transverse passageway for the shunted air through the heating duct 11 and across the path of the air which is forced therethrough.

The damper 17, as shown, comprises an oblong plate pivoted at 18, 18 on a supporting plate 19 which except for the opening regulated by the damper plate 17 closes the top of the duct 13.

Means for operating the damper plate from the front of the machine is provided and as illustrated comprises an arm 20 secured to the damper plate 1.7 rigidly, a rod 21 pivoted to said arm at one end and having at its other end an adjustable connection by means of a thumb-screw 22 with a slotted plate 23 secured at its opposite ends to the walls of the discharge duct 12. By manipulating the thumb-screw 22 back and forth in the slot 23 of the plate 23, the damper plate 17 may be tilted to and retained at any desired angle.

A water pan 24 is, as shown, disposed on the base beneath both the main and shunt ducts so that the water will form a waterbattle for both streams of air and will free both streams from dust before the mixed streams are forced upwardly through the discharge duct. The pan 24 may be inserted through a door 25 at the bottom of the discharge duct which is hinged at 26.

Having described my invention, I claim:

1. A ventilator unit embodying an airintake, a blower and means for rotating the same,means for dividing the air supplied eas es by the blower into a downwardly-moving main stream and a parallel shunt-stream, means for heating the main stream, means for regulating the volume of the shunt stream, means for causing the shunt stream to traverse transversely the path of movement of the main stream to cause a positive mixture thereof and means for discharging the mixed air upwardly and parallel to said main stream.

2. A ventilating unit embodying a housing provided with an upper compartment and a lower compartment, the upper compartment having an air intake, a blower and means for rotating said blower, and the lower compartment having partitions dividing the same into a main duct, a discharge duct at one side of said main duct and a shunt duct at the opposite side thereof, a

heater within the main duct, means for regulating the supply of air to the shunt duct, and a passageway through the main duct communicating with the shunt duct on one side and with the discharge duct at the other.

3. A ventilator unit embodying, in combination, a housing provided with an upper compartment and a lower compartment, the upper compartment having an air-intake, a blower and means for rotating the blower, and the lower compartment having two parallel vertically-disposed partitions dividing the same into a centrally-disposed main duct, a shunt duct at the rear side of said main duct and a discharge duct at the front side thereof; the shunt duct having a damper plate movable to regulate the supply of air thereto; the discharge duct having a dischargeopening at its upper end; and the main duct having a heater within the same,

and one of the walls of said main duct havwitnesses.
